The motors to the left have 9 tooth gears just like the original Bosch. You have to slightly modify the regulator, doing away with the transmission, to accept these on early Avantis. The late 70's and 80's (steel bumper) cars used a different motor and regulator than the Bosch and United Technologies, so the adaptation is easier. You also need to install polarity reversing switches which draw much less current that the originals. The burned up motor above was replaced with a Dorman product that dried up somewhat quickly after getting the one installed. The passenger side recieved a Siemans product , which also went away after I tried to get a couple others. The only other motors that were viable were the Ford Truck ones here. They use neodymium rare earth magnets making the motors smaller but just as or more powerful. The mount points are similar but I never went into the adaption of these any further. There IS one Avanti Owner locally who adapted these to his '83 Avanti.

Two GM Power Window Switches
These were used in researching
how to adapt GM/Ford motors to
our power windows
They were abandoned because of
the complexity and heavy wiring required
